The PCs leave the ark to explore the Dark Castle. There they find an ancient crown guarded by a security robot. They destroy the robot and take the crown.
On their way back home, the PCs spot a rusty ship anchored in the murky waters of a nearby river. They approach the ship and meet a trading community inhabiting its hulk. They're surprised to see an intelligent, talking bear, who seems to have information about Eden. They also speak with Nilkin, the diminutive leader of the trading post, trying to gauge if this discovery is of any use for their Ark.
